Tkáňový odběr a přírodní studie neuroendokrinních novotvarů (NEN) včetně adrenokortikálního karcinomu (ACC)

Background:

Neuroendocrine neoplasm (NENs)are rare cancers arising from the neuroendocrine cells and can affect almost any part of the body. They vary from low grade neuroendocrine tumors (NETs) to high grade neuroendocrine carcinomas (NECs). These tumors often occur in the gastrointestinal tract, pancreas, lungs, adrenal medulla (pheochromocytomas) or adrenal cortex (adrenocortical cancer) and other areas of the body mentioned below:

• Gastroenteropancreatic neuroendocrine tumors (GEP-NET): stomach, duodenum, pancreas, colon, appendix, etc.
• Liver and gallbladder
• Adrenal tumors
• Pituitary gland
• Thyroid gland: medullary thyroid carcinoma
• Parathyroid tumors
• Pulmonary neuroendocrine tumors: typical and atypical carcinoid, small cell lung cancer (SCLC), large cell neuroendocrine carcinoma (LCNEC)
• Extrapulmonary small cell cancer
• Peripheral nervous system tumors: paraganglioma, neuroblastoma)
• Breast and genitourinary tract

Their rates are rising in the United States and worldwide. Researchers want to learn more about NENs through this natural history study.

Objective:

To study the natural history of people with NENs and obtain samples from them to learn more about the disease. The clinical management of all NETs is not standardized, with only a few FDA-approved therapies and we would like to learn which combination therapeutic approach should be used, how long treatment should be continued, and in what subgroup of NENs a particular treatment option should be used.

Eligibility:

People aged 18 and older who have or are suspected to have NENs or ACC.

Design:

Participants will be screened with a medical history.

Participants will have a physical exam. Their symptoms and their ability to perform their normal activities will be reviewed. They will have blood and urine tests.

Participants will receive recommendations for managing their disease and potential treatment options. They will be able to ask as many questions as they would like.

Participants may provide saliva and blood, a for research. They will give tumor samples from a previous surgery or biopsy.

Participants may have optional biopsies. During biopsies, cancer tissue will be obtained using a needle and syringe. Tissue will be taken from the liver, lung, or a lymph node. Participants may have an imaging scan or ultrasound to help locate the tumor or area to be biopsied. They will receive local anesthesia and may be sedated.

Participants will complete a questionnaire about their family medical history.

Participants will have follow-up visits every 12 months. They will have physical exams and give samples. If their health changes, they may have extra visits. If they cannot visit NIH, they (or their doctor) will be contacted by phone or email.

Participants will take part in the study for all their life.
